The trouble begins when, during a Three Musketeers parody, Daffy suddenly notices the background has disappeared, leaving only empty space. He complains to the animator, who then puts him through an ever-changing series of locations, from a barnyard, to snow-covered fields to a tropical island. Daffy tries to adapt, apologizing to the audience for the trouble, but grows increasingly flustered as the changes continue. Soon he and the silent, faceless animator -- Daffy can only see a brush and a white glove -- are arguing over other aspects of the production, from the background colors to the definition of a close-up. Director Chuck Jones and writer Michael Maltese have a great deal of fun with this reflexive premise, gleefully poking fun at the process of animation itself while building towards a superb final punchline. Highlights include the transformation of Daffy's voice into strange sound effects and an improperly adjusted frame line that allows Daffy to get into an argument with himself.
